LEO EHRLIOH, OF ST. LOUIS, MISSOURI, ASSIGNOR TO THE AMERICAN ROLL PAPERCOMPANY, OF SAME PLACE.

PAPER-CUTTER.

SPECIFICATION forming part of Letters Patent No. 405,402, dated. J' une18, 1889.

Application iiled June 30, 1888. Serial No. 278,608. (No model.)

To all whom it may concern:

Be it known that I, LEO EHRLICH, of the city of St. Louis, in the Stateof Missouri, have invented a certain new and useful Improvement inPaper-Outters, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, and in which Figure I is a front elevationof my improved machine. Fig. II is a side view. Fig. III is a detail topView. Fig. IV is a front elevation showing a modified form. Fig. V is anend view of the same, and Fig. VI is a detail top view.

My invention relates to an improvementin machines for holding andcutting'wrappingpaper; and my invention consists in features of novelty,hereinafter fully described, and pointed out in the claims.

Referring to the drawings, l represents a suitable base; 2, end piecesorstandards; 3, a roller upon which the paper e is wound, and 5 across-piece secured to the upper ends of the standards 2.

6 represents spring-arms secured to the cross-piece 5, and to thelowerfends of which the knife 7 is secured, as shown clearly in Fig. I,the knife being'e preferably secured to the spring-arms by means of arod or bar 8, which is directly connected to the springarms by rivetingor otherwise, and to this rod or bar the knife 7 is secured by inturnedends 9, the ends preferably passing through perforations in the bar orrod and riveted at l0, Fig. III.

It will be seen that the knife 7 is situated a distance from the roll ofpaper and does not bear upon the roll, but the bar or rod 8 does bearupon the roll, and gives the proper tension to prevent the too freemovement of the roll.

l1 represents a rod or small wire bail, secured, preferably, to the arms6, as shown in Figs.I and II, and which extends from the arms in anoutward direction to the ends of the roll, and then passes across infront of the roll, as shown in Fig. I. The end of the paper is passedover this wire, as shown clearly in Fig. II, and the wire holds the endof the paper away from the roll, so as to form an easy fingerhold, asshown at l2, Fig. II. When a piece of paper is wanted, the end l2 istaken hold of, and when the desired amount of paper is pulled out it issevered by moving it upward against the knife, as shown in Fig. I and bydotted lilies in Fig. II.

I'Vhile the bar or rod 8 gives a tension to the roll of paper, it doesnot afford apositive means of preventing the backward movement of theroll. To accomplish this I pivot an eccentric 13 (made, preferably, inthe form of a disk) to one end of the knife 7, or to any other suitablesupport in proximity to the end of the roll of paper. I prefer securingit to one end of the knife, (this is shown clearly in Fig. IL) it willin this way always bear against theouter portion of the roll and beautomatically moved inward toward the center of the roll as the paper isremoved-that is, it moves inward in this direction as the paper is takenoff. The large part of this eccentric is on the retreating side of theroll of paper, as shown in Fig. I, so that as the roll of paper is movedin the direction indicated by the arrows the cam will not interfere withthe turning of the roll, but will prevent its turning in the otherdirection, or a backward direction.

The cam may be provided with a rubber band le, if desired, and may alsobe provided with a handle l5, by which it may be turned in the directionindicated by the small featherless arrow in Fig. I, to allow thebackward tu rnin g of the roll in case it should be desired to turn itbackward. The cam will have a tendency, of course, to move the roll ofpaper endwise in a direction away from it. To prevent this movement ofthe roll, I secure a bracket lto the rod 8 at the side of the machineaway from the eccentric, (see Fig. IIL) which will act to prevent t-hemovement of the roll away from the eccentric 13.

In Figs. IV to VI, inclusive, I have shown the cam 123 and bracket 16applied to what is known in the market as the Hopkins paper-cutter, theeccentric being' journaled to one end of the knife 2O by a pin 2l, andthe bracket 16 being secured to the other end of the knife by a rivet22.

I claim as niy inventionl. In a paper-cutter, the combination of asuitable support,a roll of paper, a knife l0- cated a distance from theroll of paper, and a Wire bail located just beneath and adjacent to theknife for supporting the end of the paper, substantially as and for thepurpose set forth. A

2. In a paper-cutter, the combination of a suitable support, a roll ofpaper, a suitable knife, and an eccentric eain bearing against the endof the roll of paper to prevent its retrograde movement, substantiallyas and for the purpose set forth.

3. In a paper-cutter, the combination of a suitable support, a roll ofpaper, a suitable knife, and a cam pivoted to a suitable support at oneend of the roll of paper and bearing against the roll of paper toprevent its retrograde movement, substantially as and zo for the purposeset forth.

4. In a paper-cutter, the combination of a suitable support, a roll ofpaper, a suitable knife, and a cam pivoted to a suitable support andprovided with an elastic band and 2 5 knife, an eccentric located at andbearing 3.o

against one end of the roll of paper, and a bracket located at the otherend of the roll of paper, substantially as and for the purpose setforth.
